IMPROVEMENT IN LOONIS FOPI.,WEAVI NG TRIMMINGS.

To all whom it may concern.:

Be it `known that I, LoUIs D. VALE'ITON, of the city and county of Philadelphia, `State of Pennsylvania, have invented certain Improvements in Looms for Weaving Braids or Trimmings 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had Vto the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to a mode of producing braids or trimmings having a succession. of loops on one or both sides; and my invention consists in the employment of one or more rods, or their equivalents, arranged and operated in conjunction with the warp and weft threads, substantially as described hereinafter.

vMy invention further .consists in the employment ofhooked rods arranged and operated in conjunction with certain spindles,herein` after described, for distending the warpthreads.

In order to enable `others skilled in the art to make and use my invention, `I will now proceed to describe its construction and operation. Y

On reference to theaccompanying drawings, which form a part of this specification, Figure lis a sectional elevation ot' part of a loom with my improvements; Fig. 2, a plan view; Fig 3, a detached sectional view, and Figs. 4 and 5 diagrams showing the progressive for mation ofthe trimmings.

Similar letters refer to similar parts throughout the several views.

A and A' are portions of the two side frames of a loom, each frame having an upright, C, and the two frames being connected together by the breast-beam B, warp-beam B', crossbar m, and other stays, which it has not been deemed necessary to illustrate and describe.

lo the verticals C and C' are vsecured suitable plates or brackets a, and to these is hung the lathe D, having a reed, E, of a character suitable for the fabric to be produced.

In the vertical guides F F', secured to the side beams, A A', slide the bars G and G', to which a vertical reciprocating motion is imparted from any operating part of the loom by suitable appliances, and from the under side ofthe bar G' and the upper side `oi' the bar G project the hooked rods b :and b' ande and o.

In a stationary frame, H, at the rear ofthe loom, turn the spindles I and I', to which an intermittent revolving motion is imparted by any suitable mechanism. From the ends of each spindle project two rods, i and t', each rod having at the end an eye, the use of which will be described hereinafter. Two rods, K and K', are loosely connected by a pin, n, to a slotted bracket, J, secured to the breast-beam,

the outer end of each rod being .bent down at` right angles, as shown in Fig. l. A cord or cords, h, are secured to each rod, and these cords are so operated from any working part ofthe loom as to be the medium of imparting the movements described hereinafter to the rods K and K. projects a `bent rod,j`, upon which the rods K and K' rest, and to each corner, 2, of thisrod is secured olle end of a spring, 3, the `otherend of which is attached to one ofthe rods K.

A roller, L,.turns in brackets projecting fromr the inside of the breast-beam, and below this roller revolves the take-up roller M. Each pair of threads ,m and g/ ot the four threads, which constitute the warp in the present instance, is. twisted together, and each ofthe doubled threads is` conducted from the spool or bobbin, upon which the supply is wound,

through one ot' the spindles, l, in front .of` which thetwo threads areseparated,the

thread at passing through the eye of the rod t' and the thread y through the eye of the rod i. The threads from each spindle pass from the rods t' through the reeds E, and thence over the roller L to the take-up roller M. The weft-thread c' is shown by red lines in the drawings, and is carried by a shuttle similar to those used in ordinary coach-lace looms.

Operation: In the drawings, a portion of trimming is represented as havin gbeen formed,

From. the breast-beam B` 2 n tasas the lathe is carried forward so as to beat up the weft, after which the bars G and G are brought to the position shown in Fig. 3, so that the threads w and y are released and occupy the position shown in Fig. 4. The spindl( s I and Il are now turned one-half of a revolution in thedi'rection of their arrows, so that the two threads a: and y from each spindle shall be twisted at the rear of the weftthread in the manner shown in Fig. 5, the

weft-thread beingvthus interlocked with the warp-thread. The rod Kis now raised by the cord h, and as it escapes from the loop it is Y thrown forward by the action of the spring 3 to the position shown in red lines, Fig. l, so that when the said rod, at the next movement, drops tothe position shown by dotted lines its bent end shall be in the rear of the weftthread 2. The lathe is then moved back and the Warp-threads (listen-ded, the thread x being depressed and the thread y elevated, owing to the change in the position of the threads effected by the partial revolution of the spindies I and l'. The shuttle now passes between the warp-threadsin theIdirection pointed out by the arrow, Fig. 2, folding the thread i round the end of the rod K and carrying it to the position shown by dotted lines, Fig. 2.

. The lathe now beats up the weft-thread, the

bars G again assume the position. shown in Fig. 3, and the warp-threads are twisted as before. The rod K' is now raised by the cord h and thrown'forward by the spring 3 to the position shown by red lines, Fig. l, so that it shall descend with its bent end in the rear of the weft-thread, whichl is drawnl round it by the neXt movement of the shuttle. As the lathe again beats up the Weft-,the roller M takes up sufticicnt of the work to carry the rods K back to the position shown in Figs. 1

and 2, so that when they are released from the loops the springs 3 shall throw them toward the lathe, as before. It will be seen th at each t me the weft thread is carried round the end of one of the rods K, and secured by the twistirgof the warp-threads and beating up of the` latter, a loop of the weft-thread is formed on one side ofthe warp, a similar loop being Afabric by causing the rod to be so operated that it will move from one side of the warp to the other.

The pattern of the fabric may bevaried by using additional shuttles and by the employment of additional warp threads 'of different colors.

In many cases the revolving spindles I and hooks b and c may be dispensed with and the ordinary harness and treadles used. When, however, the warp-threads are twisted to secure the weft, the ordinary harness cannot be employed, and Without the hooks b and c it would be necessary to arrange the rods t' so far apart in order to distend the warp sutticiently for the shuttle to pass, that a limited number only of spindles could be used in the space which they must occupy. I claim as my invention and desire to secure by Letters Patentl. One or more rods, K and K, or their equivalents, arranged and operating in conjunction with the warp and weft threads of a loom, substantiallyY as and for the purpose set forth.

v 2. The hooked rods b and c, arranged and operating in conjunction with the spindles I,`

for distending the warp-threads, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. '1
